Objective To investigate the correlation between human leukocyte antigens-A,-B,-DRB1 (HLA-A,-B,-DRB1) high resolution alleles and chronic renal failure (CRF) caused by immunoglobulin-a nephropathy (IgAN).Method The polymerase chain reaction-sequence-based typing (PCR-SBT) method was used to investigate the genotypes of HLA-A,-B and-DRB1 high-resolution alleles in 191 cases of CRF caused by IgAN (experimental group) and 503 healthy blood donors (control group).The alleles frequencies between two groups were compared and the association between CRF caused by IgAN and the polyrnorphism of HLA was analyzed.Result (1) There were 25 alleles at A locus,48 alleles at B locus and 32 alleles at DRB1 locus in experimental group.(2) The genetic frequency of HLAA * 2901 [Pc =0.033,OR =10.738,95％ CI (1.193,96.691)],HLA DRB1 * 1106 [Pc =0.0001,OR =0.969,95％ CI (0.944,0.994)],HLA-DRB1 * 1202[Pc =0.002,OR =1.859,95％ CI (1.259,2.745)],HLA-DRB1 * 1401 [Pc =0.021,OR =0.984,95％ CI (0.967,0.998)],HLA-DRB1 * 1602[Pc=0.015,OR=1.915,95％ CI (1.157,3.17)] in experimental group was higher than in control group (P＜0.05).Conclusion There is susceptibility association of HLA-A * 2901,HLA-DRB1 * 1106,HLA-DRE * 1202,HLA-DRB1 * 1401,HLA-DRB1 * 1602 with CRF caused by IgAN.It is concluded that there is a close genetic and immunological correlation between HLA alleles and the pathogenesis of CRF caused by IgAN.

ObjectiveTo evaluate the effect of rehabilitation nursing in the peri-operative period of the first-stage combined anterior-posterior approach surgery in the sacral tumor resection.Methods15 patients with sacral tumor received psychological intervention, gastrointestinal preparation, exercises of perineum sphincter contraction and relaxation training before the operation. Changes of patients' vital signs and nerve function were observed after the operation, and rehabilitation training and instruction were performed.ResultsAll cases were followed up for 2～37 months. Except one case died of tumor transfered to lung, all of other cases had a satisfactory curative effect in the near future, and their local symptom released and the functions of urination and defecation were kept well.ConclusionRehabilitation nursing in the peri-operative period plays an important role in surgical treatment of sacral tumor. It affects the rehabilitation and function restitution obviously and can reduce the occurrence of complication effectively.

Objectives To assess treatment outcomes and prognosis in infants with atrial flutter (AFL).Methods Thirty-four (34) cases of infants with AFL in Hunan Children's Hospital had been analyzed for clinical features, treatment outcomes and follow-up between March, 2009 and September, 2015. Based on ECG characteristics, the patients had been divided into simple and complex AFL groups. Based on age, they had been divided into neonates and non-neonates group. The aim of this study is to compare the clinical effects of drug treatment in different types of AFL.Resultsb With digitalis alone, the cardioversion rate was 37.5%,no signiflcant difference was observed between simple and complex AFL groups (45.8% vs 12.5%,P=0.206). Combining with other drugs, the cardioversion rate was 54.5%, which showed signiflcant difference between simple and complex AFL groups (76.9% vs 22.2%,P=0.036). The overall cardioversion rate was 70.6%, which showed signiflcant difference between simple and complex AFL groups(87.5% vs 30%,P=0.003). There was no signiflcant difference in pharmaceutical cardioversion rate between neonates and non-neonates group (85.7% vs 60.0%,P=0.216). Two cases with symptoms of heart failure used synchronized cardioversion. One patient restored to sinus rhythm, and another case was still recurrent of AFL after repeated electrical cardioversion, and eventually died of cardiogenic shock. After treatment, 9 patients were still with paroxysmal AFL and atrial tachycardia episodes, including 3 cases of simple type and 6 cases of complex type who were discharged with oral digoxin and propafenone treatment at home. 24 patients were followed up (3 months to 3 years and 4 months). 16 cases restored to sinus rhythm during hospitalization had no recurrence of AFL.Conclusions The overall treatment effects of AFL in infants were good. In simple type of AFL, most of patients did not need long-term antiarrhythmic drug therapy and the prognosis was good. The prognosis of treatment with conventional drug was poor in complex AFL group, with a higher rate of recurrence of AFL.

Background Rapamycin(RAPA)is a specific inhibitor of the mammalian target of rapamycin (mTOR).Researches showed that RAPA inhibits the proliferation of lens epithelium cells(LECs)and tumor cells and induces apoptosis of tumor cells.To investigate whether rapamycin has the inhibitory effect on retinal pigment epithelium(RPE)cells is very important for the prevention and management of proliferative vitreoretinopathy (PVR).Objective This study was to investigate the effects of RAPA on the proliferation and apoptosis of human RPE cells in vitro.Methods Human RPE cells(D407 strain)were cultured and passaged and then divided into regular culture group(blank control group),DMSO control group(0.1‰ DMSO +regular culture),and different concentrations RAPA-treatment groups(5,10,20,40,80,160,320 nmol/L).The proliferation(A490)of human RPE cells was detected using MTT,and the inhibitory rates of RAPA on the proliferation of RPE cells were calculated and compared among different groups at 12,24 and 48 hours.The apoptosis rates of the cells were analyzed among various groups by Hoechst staining after 12,24,48 hours.Results The inhibitory rates of RAPA on RPE cells were significantly different among various groups(F=484.451,P＜0.01)and evidently elevated in 20-320 nmol/L RAPA groups compared with DMSO control group(P ＜ 0.01).The inhibition of RAPA on the cells was considerably enhanced as the lapse of time(F=232.262,P＜0.01)with more dominant effects in 24 and 48 hours compared to 12 hours after addition of RAPA(P＜0.05-0.01).Compared with blank control group and DMSO control group,the apoptotic rates of the cells were evidently increased in 12,24,48 hours in 10 nmol/L RAPA group(all P＜0.05),and higher cellular apoptotic rates were found in 20-320 nmol/L RAPA groups(all P＜0.01).The alteration of cellular apoptotic rate showed a gradually incremental trend as the acting time of RAPA(F =625.584,P＜0.01).Karyorrhexis and mass-like density staining and chromatin substance were seen in RPE cells under the fluorescence microscope in ≥ 10 nmoL/L RAPA groups.Conclusions RAPA suppresses the proliferation and induces the apoptosis of human RPE cells in concentration-and time-dependent manner in vitro.

Objective To explore CT manifestion of multiple primary lung cancer (MPLC)and to improve the recognization of MPLC.Methods The CT manifestions of 12 cases with MPLC proved by pathology were retrospectively reviewed.Results All the 12 cases were double primary lung cancer.There were 24 lesions with 21 peripheral and 3 central,the average diameter was (2.2 ± 0.6)cm.Lesions located in contralateral lobes were in 2 patients,and located in ipsilateral lobes were in 10 patients,with 3 located in the same lobe and 7 in the different lobes.There were 7 cases of adenocarcinoma-adenocarcinoma,3 cases of squamous cell carci-noma-adenocarcinoma,1 case of squamous cell carcinoma-squamous cell carcinoma and 1 case of squamous cell carcinoma-carcinoid. 1 1 cases were metachronous and 1 case was synchronous.3 lesions were lump located at hilus of the lung,21 lesions were intrapul-monary nodules,showing masses with lobulated shape,spicules of margin,vascular convergence,vacuole and pleural indentation sign.Most foci displayed moderate intensity enhancement and homogeneous density in triphase enhanced scans,the CT value of le-sions on enhanced images ranged from 20-60 HU.Conclusion MPLC are synchronous and peripheral adenocarcinoma type,all of the lesions have typical CT features of primary lung cancer.
